#18418 new defect

Broken display output for guest application entering full screen mode with changed resolution

Steps to reproduce:

Install guest OS, install guest addons
Have guest OS in maximised window (not full screen)
Start application (a game in my case - Heroes of Might and Magic IV, DirectX 9.0c)

Expected result: Application should be started, due to its lower resolution it should be surrounded by unused area (like when OS boots).

Actual result: Guest display is broken.
